TRUCK.

Specification of Letters Patent. A Patented Apr. 19, 1921-.

Application ledDecember 22, 1919. Serial No. 346,722.

To all 'whom-vit may concern Be itrknown that I, WALTER C. OR'rGmR, acitizen of the United States, residing in the Vcityy of Wichita Fallsand State of Texas, have invented new and useful Improvements in Trucks,of which the following is a speciication.

.This invention'relates to trucks. In the usual'method of unloadingbricks or other materials which must be handledin unloading them, thebricks must be carried lor thrown fromthe remote points on the truck,Vto a man standing at the'side ofthe truck who receives the bricks fromthe man standing on the truck. This manner of unloading a Vtrucknecessitates'the use of two men.

The4 general objectof the yinventionis to .y produce a truck soVconstructed that it can vbe quickly unloaded by one manstanding on thegroundV at the side of the truck, and unassisted by anyone on the truck.'Io this end the invention concerns the construction whereY theunloading is taking place.

of the truck, which is such that it enables Y the load on the truck doorto be moved from time to time toward the side of the truck In this waythe load on the truck is constantly within reach of the man standing onthe ground at the side of the truck. I am aware that it has beenproposed to construct a Y Y truckwith a Hoor movablelongitudinally ofthe truck.V Such a Vconstruction necessitates verylfrequent movement ofthe floor in unloading. the truck, and furthermore, it does not render.yall portions of the truck so accessible as .where the truck unloadsfrom the A side, asinmy invention. While vmy truck is 4,capzatble'ofbeing unloaded quickly by one man, it also can beused with facility byone Vman to place a load on-the truck: Furthermore, in the type of truckin which the unloadingnis. effected at the rear of the truck,

there is considerable difficulty in supporting the movable flooralongthe longitudinal orv middleline of the truck, ordinarily'neces-"sitating the useV of a frame bar which considerably increases theweightJ and difficulty of. constructing the truck." According ,to my"invention, Iprovide a plurality of comparatively light transverse'girders, supporting sectionsof the floor, and the distance betweenthesegirders and between the girders ,and .the ends of thertruck can bereadily v'adaptedto the fuses or -thef requirementsV of differentloading conditions. On account of the factthat this truck can be readilyloaded or unloaded by a single workman,

great economy results from the use of the truck.

A further object of the invention is to produce a truck of simpleconstruction having a movable floor forthe purpose described, soorganized as to enable the load to be etliciently supported, and in sucha way as to Venable a relatively light frame to be employed forsupporting the'movable floor.

Further objects 'of the invention .will appear hereinafter.

The invention consists in the general combination of parts and inthenovel features of -the parts hereinafter described, all of vhiclxicontribute to produce lan eiiicient ruc , A preferred embodiment of myinvention `will be particularly described in the followsection tails ofthe preferred construction;.and

Fig. 5 is a side elevation of the lever which I may employ for-effecting the movement of the truck floor and the load carried by it.

Referring more particularly'to the parts, the truck comprises a frame lvhaving two side bars 2 which may be of channel crosssection (Fig. 2).In applying my invention I provide a plurality of transverse Ofirders,(see Fig. 3) including end girders 4 which are ldisposed adjacent theends 5 of the truck, and one or more intermediate girders 6 which arepreferably disposed equidistant from each other and equidistant from theend girders 4. These girders are of skeleton or built-up type, and eachgirder comprises a bottom rail 7 which rests upon, and is fastened tothe side b ars 2 of the iframe. In the end girders these bottom rails '7simply consist of angle irons, butin the intermediate girders 6 eachbottom rail comprises two angle irons 7 and 7b placed back to back, andattached respectively on opposite sides of the girder. Between the angleirons 7a and 7b, vertical braces 8 are provided, the upper ends of whichareV riveted between angle irons 9a and 9b which are back to back, andwhich constitute the upper rail or floor-rail 9. In the end girders 4,

,the upper rail 9 iscomposed of a single angle iron.

Near each side of the truck a lon,f ,itudinal` i as shown, and arecomposed of links 13a, the

pivot-connections of the links being provided withY rollers 14.

To the links there are attached floor boards 15, and these floor boardsextend longitudinallyY and are intercostal between the girders so as toform a complete floor composed of a plurality of floor sections.y

The horizontal flanges of the angle irons 9a and 9b support the upperruns of the chains and the floor; and the corresponding flanges of theangle irons 7@ and 7 b support the lower runs of the chains and guidethem over the si-de bars 2.

About on a level with the floor line of the truck and at each side,there is provided a Asill 16 which is in the form of an angle ironrunning longitudinally from end to end of the truck. l I providelongitudinally disposed side girders 17 which may be of wood, and thesegirders are supported at their lower edges on the ends of the rails 7.

Each transverse girder is provided at each `end with a gusset plate 18which is riveted to the lower rail 7 and to -the upper rail 9 y (seeFig. 4). These plates operate as bearp ings rfor the longitudinal sideshafts 10, and

the outer end of the upper rail .9 carries a Vlongbolt 19 whichpassesthrough the adj'acentside girder 17, being secured to the girderby nuts 20 seating on its V'ertical faces.

`At suitable points the side girders 17 are provided with sockets 21which receive side panels 23 which consti-v stakes 22 carrying tutesections or side panels of the sides of the truck.` These panelscorrespond to the spaces between the transverse girders.

The vertical bars 8 ofthe girders are connected together by suitablelongitudinal tie bars 24. A. similar tie-bar 24n connects the foremostintermediate girder to the forward vend of the truck. It is unnecessarythat the will be moved toward the side of the truck, VYthereby carryingthe load laterally so as to move it into reach of the man standing atthe side of the truck. The truck isprovlded with a removable tail-board29 which carries stakes 30 which are received in suitablestake-sockets31. e i

In order to enable the truck fioor to be moved at will toward one sideor the other of the truck, to facilitate unloading the truck 1n themanner suggested above, I prefer to let the two side shafts 10 extendbeyond the rear end girder of the truck 32 (see Fig. 1), and I providethe ends of the shafts 10, respectively, with sprocket wheels 33 and 34.And I provide .a ratchet lever 35 which has a hub at one end, which isattachable to each shaft 10 by sliding it over the exposed end of theshaft. The lever is provided with a double pawl 37. In Fig.

5 one end of the double pawl 37 is illustrated as coperating with theratchet wheel 33. Evidently by raising this lever and pulling it downthe ratchet wheel 33 can be rotated in a clockwise direction, the effectof which would be to move the Hoor toward the righthand side of thetruck. Fig. lshows the lever 35 mounted in position to coperate with theratchet wheel 34. The teeth of the ratchet wheel 34 projecttoward theright hand side of the truck on the upper side of the ratchet wheel,from which arrangement" it follows that the operationof the ratchetlever 35 in coperation withfthis ratchet wheel would produce theopposite effect from that resulting from the use of the ratchet vwheel33. That is tosay, the truck floor through the medium of the ratchetwheel 34, can be moved toward the leftside ofthe truck. The rear endboard 32 of the truck carries'a suitable socket 33 to support 4 the endof the lever 35 when the same is not in use. Y

In usin the truck the driver stops the ltruck so t at its side isdisposed adjacent to the unloading platform or curb at which theunloading is to occur. He then removes the panels 23 and unloads thebricks or other articles at the edge of the truck, reaching Vin over theHoor" of .the truck as far as possible. AfterV he has removed all of thebricks he canreach, he then operates the lever 36 so as to bringtheremaining bricks over toward the side of the truck. He then proceedsas before to remove all of the bricks he can reach. In this way with oneor two advancings of the Hoor the driverV ters Patent is:

1. In a truck, the combination of a frame including two side barsextending substantially parallel with the longitudinal axis of thetruck, a plurality of transverse girders resting upon and supported. bythe upper edges of said side bars, movable chains disposed in coperatingpairs, carried on said girders, iioor boards between the girders andconnecting the pairs of chains, extending substantially parallel withthe side bars, and constituting a substantially horizontal Hoor for thetruck, a removableside board for the truck, and means independent of thewheels lof the truck for moving the chains to advance the loor towardthe removable side board.

2. In a truck, the combination of a Jframe, including two side barssubstantially parallel with the longitudinal axis of the truck, aplurality of transverse girders resting upon and supported Vby the upperedges of said side bars, with their ends projecting beyond' the sidebars, endlesschains, disposed in ooperating pairs, Hoor-boards betweenthe girders connecting the pairs of chains, extending substantiallyparallel with the side bars and constituting a substan- 'tiallyhorizontal floor rfor the truck, said girders each having a bottom railfor supporting and guiding the lower runs of the endless chains, andanupper rail for supporting the floor and the upper runs of the chains,and means independent of the wheels of the truck and constructed to beoperated at will for moving the chains to advance the floor toward theside of the truck.

3. In a truck, the combination of a frame, including two side barssubstantially parallel with the longitudinal axis of the truck,

a plurality of transverse girders resting upon and supported by theupper edges of said side bars, said girders each comprising a lower railcomposed of a pair of angle irons attached respectively at oppositesides of the girder, and an upper rail composed of a pair of angle ironsattached at opposite sides of the girder, said angle irons havinghorizontal ianges, endless chains disposed in coperating pairs andhaving upper runs resting on the horizontal flanges of the upper rails,floor-boards between the girders connecting the pairs of chainsextending substantially parallel with the side bars and constituting afloor for the truck, supported on the upper rails, and means independentof the wheels of the truck and constructed to be operated at will tomove the chains to advance the ioor toward the side of the truck.

In testimony whereof, I have hereunto set my hand.
